newline

问题 The .val() property of an item in jQuery for a <textarea> doesn't seem to work with new lines. I need this function as the text-area is meant to recognize the enter key and display it as a preview, with the new line in tact. However, what happens is shown in this fiddle: http://jsfiddle.net/GbjTy/1/. The text is displayed, but not in a new line. How can I achieve the preview to include new lines, and I know it is possible, because it does this in the Stack Overflow Post Question preview.

问题 I've been trying to figure out the best way to write binary data to stdout from a C program. It works fine on Linux, but I'm having issues when I compile on Windows because "\n" gets converted to "\r\n". Is there a standard way to write to stdout in some sort of binary mode which avoids newline conversion? If not, what is the simplest way to get Windows to stop doing this? I'm using GCC and MinGW. 回答1: You can use setmode(fileno(stdout), O_BINARY) Wrap it in an ifdef if you want to keep it

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . I'm looking for a text editor that can show me the actual carriage returns and newlines. E.g. if I save this string: "This\rIs\r\nA\nString" Instead of showing This Is A String I'm looking for some text editor which will show This\rIs\r\nA\nString I believe a problem with my text-file parsing in a certain

问题 How can I write to files using Python (on Windows) and use the Unix end of line character? e.g. When doing: f = open('file.txt', 'w') f.write('hello\n') f.close() Python automatically replaces \n with \r\n. 回答1: For Python 2 & 3 See: The modern way: use newline='' answer on this very page. For Python 2 only (original answer) Open the file as binary to prevent the translation of end-of-line characters: f = open('file.txt', 'wb') Quoting the Python manual: On Windows, 'b' appended to the mode

问题 Is it possible to have a new line in a data attribute ? I am trying to do something like this: CSS: [data-foo]:after { content: attr(data-foo); background-color: black; } HTML <div data-foo="First line \a Second Line">foo</div> I found that "\a" is a new line in CSS, but still does not work for me. 回答1: Here is how this can work. You need to modify your data attribute as follows: <div data-foo='First line Second Line'>foo</div> and the CSS (proof of concept): [data-foo]:after { content:

问题 How can I test if the string is empty in Python? For example, "<space><space><space>" is empty, so is "<space><tab><space><newline><space>" , so is "<newline><newline><newline><tab><newline>" , etc. 回答1: yourString.isspace() "Return true if there are only whitespace characters in the string and there is at least one character, false otherwise." Combine that with a special case for handling the empty string. Alternatively, you could use strippedString = yourString.strip() And then check if

问题 What's the difference between \n and \r (I know it has something to do with OS), and what's the best way to echo a line break that will work cross platform? EDIT: In response to Jarod, I'll be using ths to echo a line break in a .txt log file, though I'm sure I'll be using it in the future for things such as echoing HTML makup onto a page. 回答1: \n is a Linux/Unix line break. \r is a classic Mac OS (non-OS X) line break. Mac OS X uses the above unix \n . \r\n is a Windows line break. I usually

问题 To speed up some bash script execution, I would like to keep the result of a command in a variable using command substitution, but the command substitution replaces the 0x0A newline character by a space. For example: a=`df -H` or a=$( df -H ) When I want to process further $a , the newline characters are replaced by a space and all the lines are now on one line, which is much harder to grep: echo $a What would be the easy tricks to avoid the newline character being removed by the command
